TYPE- SPECIFICATION forming part of Letters Patent No. 640,699, datedJanuary 2, 1900. Application filed April 20,1899. Serial No. 713,773-(No model.)

To all whom it may concern.-

Be it known that LWILLIAM P. QUENTELL, a citizen of the United States,residing at Harrisburg, in the county of Dauphin and State ofPennsylvania, have invented new and useful Improvements in Type-Bars, ofwhich the following is a specification.

By means of this invention a type-head can be mounted on a type-bar of atype-writing machine so as to be readily rotatable and to be at alltimes in position for accurate or clean printing, while at the same timethe bars and heads are readily interchangeable and wear or looseness canbe taken up.

The invention is set forth in the following annexed drawings, in,whichFigure l is a longitudinal elevation of the bar with the head insection. Fig. 2is aperspective View of the bar and head. Fig. 3 is asectional plan view of Fig. 1.

The type-bar 1 is adapted to swing about any suitable fulcrum orpivot-say, for example, at the point 2-so that the type-head 3 on thebar will give a stroke or print. The head 3 has two or more faces, withcharacters or type 4, and the head is rotatable on the bar, so thatdifferent faces or type can be set to print. The bar is shown with adiminished or stem portion 5, and the part 6 between the stem 5 and bodypart 1 is shaped as a center or cone. The stem 5 is threaded for thereception of a nut 7, also shaped as a cone or center. A jam or look nut8 may also be applied.

The type-head 3 is rotatively mounted on the bar between the centers orconical bearings 6 and 7. This head 3 has a hub or center portion forthe passage of stem 5 and also has center or cone-shaped recesses madeto seat or fit the bearing 6 and nut 7. By means of this centering thehead is made easily rotatable, and the adjustable bearing 7, whichserves for mounting the head on the bar, can be set to take up wear andto prevent looseness of the head on the bar. Of course at either one orboth bearings 6 and 7 there might be ball-races for antifriction-balls;but such modifications are obvious and'such balls have not been foundnecessary. The conical or center bearings are also of advantage, as theyallow the bars and heads to be made readily interchangeable, which wouldnot be the case if a tubular hub of the head had to fit a cylindricalshaft.

The head could be rotated or set by hand or automatically, and one ormore lugs 9.can be applied for facilitating or securing rotation of thehead. A spring 10 can be applied to prevent accidental rotation of thehead.

What I claim as new, and desire to secure by Letters Patent, is-

1. A type-bar havinga type-head and 6611- ters or cone-bearings for thehead substatv tially as described.

2. A type-bar having a conical or center bearing 6 and a conical orcenter shaped nut, and a type'head rotatively mounted on the bar betweenthe bearing and nut and having center or cone-shaped recesses fitted tothe bearing and nut substantially as described.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.
